METHOD FOR PRODUCTION OF SEALED CERMET UNITS Russian patent published in 1997 - IPC

Abstract RU 2099312 C1

FIELD: technology of production of cermet units by soldering of ceramic material with metal, power engineering and radio-engineering plants and devices. SUBSTANCE: metallized alumina ceramic is soldered with the use of copper solder with metal bushing. Soldering of conical rotating unit is accomplished under flux in the air by defocused pulse laser radiation through ceramics transparent for the given wave length with simultaneous application of compression force 3-5x105.10⁵ Pa. Heating and cooling are carried out with the rate of 1-50 C/s. EFFECT: improved adaptability of enveloping cone seals due to soldering of metallized alumina ceramics by copper solder with metal bushing. 1 dwg
